This study develops and contrasts In-Home Cognitive Behavioral Therapy (IH-CBT), an adapted evidence-based treatment for depressed mothers participating in home visitation, with typical home visitation in which treatment may be obtained in the community. Mothers will be identified using a two step process consisting of administration of a screen and subsequent diagnosis of Major Depressive Disorder. The will then be randomized into the treatment and control conditions. A comprehensive assessment of depression and related areas of functioning will be administered at pre-treatment, post-treatment, and 3 month follow-up. It is hypothesized that IH-CBT will lead to broad and durable gains in mood and social support relative to those in typical home visitation.
